Hacking a Ham Radio

For Christmas, received a Baofeng UV5R radio. He didn't have an amateur radio license, so he decided to use it as a police scanner. Since the schematics were available, he cracked it open and hacked it.

This $40 radio communicates on the 136-174 MHz and 400-480 MHz bands. It uses a one-time programmable microcontroller and the RDA1846 transceiver. With the power traces to the MCU cut, was able to send his own signals to the chip over I2C using an Arduino.

Apple PowerBook 170

The second acquisition of my recently established vintage computer collection is an Apple PowerBook 170, donated to me by a coworker.

The original power supply was shot, and the NiCd battery had leaked, but I was able to find an alternate power supply and boot it up! Unfortunately, the internal SCSI 40MB drive is no longer recognized by the system, so I’ll need to find an alternative mass storage device (or just stick with the 3.5″ 800K disks that my friends have shared with me).

Inspired by The Byte Cellar (http://www.bytecellar.com/), I’ve just started building my vintage computer collection, starting with the Apple IIgs.

As you can see by the photos in the set, it is in remarkably good condition, and it came with all of the original boxes, manuals, and receipts!

Unfortunately, the original monitor is not functioning correctly (blown capacitors, I assume), so I’ve been using my DLP TV as a monitor. I’ve purchased a DB-15 to HD-15 (RGB to VGA) physical adapter and attempted to hook it up to a LCD monitor, but the scan range produced by the Apple IIgs (15.7khz, iirc) is far below the range of the LCD.

Learn a little assembly language for the 6502 processor

Evern wanted to write your own Atari 2600 games? This won't get you quite that far, but it will teach you the very basics. It's an assembly tutorial for the 6502 processor. The nice thing is that you need nothing more than your browser to participate thanks to the embedded JavaScript emulator which acts as assembler, machine, and debugger in one.

Ooh, this is exciting...especially since the Apple IIgs I recently acquired has a 65c816, which boots in 6502 emulation mode. =)

MiniBin!

Update!

e-Sushi has posted a new version of MiniBin after all! You can find the new version at e-Sushi.net (
http://www.e-sushi.net/minibin
), or you can still download the old version (3.8.3.0) below.

One of my favorite Windows utilities, MiniBin, has just been retired by its developer, so I’m creating a post here to make the download available after its binaries get pulled from the original website.

MiniBin-3.8.3.0-Setup.zip

(Thanks to Mike Edward Moras for making such a great app!)

Details from e-sushi.net:

MiniBin is a free recycle bin for your Microsoft Windows system tray area; the area next to the clock in your taskbar.

Please note that the MiniBin project has ended. This means: no more updates and no more support. Yes, I know… but it had to end somewhere. MiniBin was first published in 2004 and enjoyed updates until 2012. As it’s bug-free and feature-complete in it’s current state, I decided it’s time to move on to new horizons.

For the time being, you can still download the final version of MiniBin, the recycle bin for your system. But this download will vanish into the void within the not so far future. So, get it while it’s still available!

Editra: Setup as a Python IDE

I can’t believe that I had overlooked this application at first, but I’m glad that I finally started using it. So far, this is the best free Python IDE that I’ve found, and it’s a fantastic general text editor as well!
